摘要： A multilayer ceramic electronic component includes a ceramic body including a dielectric layer, first and second internal electrodes disposed to face each other with the dielectric layer interposed therebetween in the ceramic body, and first and second external electrodes disposed on external surfaces of the ceramic body and electrically connected to the first and second electrodes. At least one of the first and second external electrodes includes a first electrode layer including a first glass and a second electrode layer disposed on the first electrode layer and including a second glass. The first glass contains a larger amount of barium-zinc (Ba—Zn) than the second glass, and the second glass contains a larger amount of silicon (Si) than the first glass.
